In an area within 25 m or so of the springs at the head of the Ebbsfleet, and partially overlying the early Roman road towards the springs was a series of structures. The earliest measured approximately 6.5 m by at least 4 m, with a floor made largely of clay but partly of chalk and a hearth near the centre. This has been assigned to the last quarter of the 1st century AD. A later phase of construction assigned a construction date in the early 2nd century with its destruction occurring in the decades nearer the middle of the 2nd century.
